Yeaterday i was a hired hand for moving. Waiting on the time to leave after everything was moved in; i was sitting in the pick up truck. The drivers door was ajar so the alarm was on. I took in the scenery and looked in diferent placesof sight. The head movement i was using amplified the alarm. Testing the sound i moved my head in study of the noise. Every movement beyond resting position incresed the volume in my head.
If we were to take body language in conversations while being the reciever of words then it may be that we can hear better. A different study could be the sender of words. And how their sounds change.
I cant be sure if the quality is better but it is deffinitly louder for sounds of an alarm.
